An international collaboration in which researchers from the Instituto de Astrofísica de Canarias take part, has discovered a unique planetary system made up of six exolplanets, of which five perform an unusual rhythmic dance, while they orbit their star. Even so, the sizes and masses of the planets are not in any ordered pattern. This finding, which is published today in the journal Astronomy & Astrophyisics, poses a challenge to current theories of planet formation.
This section includes scientific and technological news from the IAC and its Observatories, as well as press releases on scientific and technological results, astronomical events, educational projects, outreach activities and institutional events.

Collision of C-type Ryugu’s parent body with a rocky object
Hayabusa2’s optical navigation camera (ONC) found many anomalously bright boulders on the dark surface of the carbonaceous (or C-type) asteroid Ryugu. Observations with ONC and the near-infrared spectrometer (NIRS3) indicates that at least six of those bright boulders exhibit reflectance spectra consistent with exogenous origin; their spectra are similar to rocky (or S-type) asteroids. This means that the bright boulders resulted from collisional mixing between Ryugu’s parent body and S-type asteroid(s). On Bennu, the asteroid explored by NASA’s OSIRIS-REx, bright boulders with spectraAdvertised on
Successful launch of DRAGO, IACTEC’s first infrared camera
This afternoon the DRAGO infrared camera, developed by the team at IACTEC-Space, of the Instituto de Astrofísica de Canarias (IAC), and integrated into the ION satellite carrier of the Italian company D-Orbit, has been successfully launched into space on Space X’s Falcon 9 rocket. The Transporter-1 mission, as it is called, was carried out without a hitch during the first hour of the launch window which opened at 15:00 h UTC, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida (USA).Advertised on
The Gran Telescopio Canarias observes Beethoven’s musical universe
The Cabildos of La Palma and Tenerife, together with the Instituto de Astrofísica de Canarias (IAC) present the recording of the Eroica Symphony of Ludwig van Beethoven, performed by the Tenerife Symphony Orchestra in the dome of the Grantecan, to celebrate the 250th anniversary of the birth of the composer.Advertised on
A challenge to models of star-formation truncation in massive galaxies
An international study published in Nature Astronomy, in which the Instituto de Astrofísica de Canarias (IAC) is a participant, suggests that the feedback winds do not have a direct impact on braking the formation of stars in massive galaxies, and attributes the process to other events such as ejection by huge tides caused when galaxies merge.Advertised on
Quadrantids 2021: our best wishes for the start of a new year
This astronomical event will be broadcast live in the early hours of January 3rd from the Canary Observatories, via the sky-live.tv channel, with the collaboration of the European Project Interreg EELabs and the Innovation Service of the Cabildo of the Island of La Palma. After the impressive data of the activity of the 2020 Geminids (the last major meteor shower of the year) the expectations for the Quadrantids are very high, even though this time the Moon will make it hard to see the fainter meteors. Usually the Geminids and the Quadrantids show activity approaching 100 meteors per hourAdvertised on
